A rotary screw compressor is a type of air compressor that uses two interlocking helical screws to compress air. As the screws turn, they trap air and reduce its volume, which increases the pressure. This design allows for continuous operation, making it efficient for industrial applications where a steady supply of compressed air is needed. These compressors are often used in factories, construction sites, and other settings where reliable air pressure is essential. They are known for their durability and low maintenance requirements, making them a popular choice among businesses that rely on compressed air for tools and machinery.
